LOCK.

Specification of Letters Patent.

Patented Sept. 17, 1907.

Application filed February 5, 1906. Serial No- 299,432.

To all whom it may concern:

Be it known that I, PHILLIP I-I. SnRIo, a citizen of the United States, residing at New York, borough of Manhattan, in the county of New York and State of New York, have invented certain new and useful Improvements in Locks, of which the following is a specification.

This invention relates to looks of that kind wherein the bolt and the tumbler-mechanism are carried by a pivoted or hinged member.

The construction is adapted for use, primarily, on trunks by attaching the hinged member to the trunkcover, and by using said member in connection with a keeper attached to the body of the trunk; but I do not desire to confine myself to this particular use, because the lock may be used generally.

One object of the invention is to provide a novel .bolt mechanism which is self locking by the operation of pressing or forcing the movable or hinged member into place relative to the keeper.

Another object is to provide a simple and efiicient bolt mechanism which provides a secure fastening by the employment of a plurality of bolts adapted to engage with the keeper at a number of points.

The invention consists ofa bolt mechanism employing a plurality of bolts, and key-actuated means for withdrawing all the bolts simultaneously. Said keyactuated means in one form of the invention includes a lever pivoted to the bolts, a turning member provided on one side with means for actuating the bolts and on its other side with a tumbler-stud; and one or more tumblers adapted for engagement with said stud.

Reference is made to the accompanying drawings, forming a part of this specification, wherein like characters of reference are used to indicate corresponding parts in all the figures.

Figure 1 is a view in front elevation showing the lock applied to a trunk; Fig. 2 is a vertical sectional elevation thereof; Fig. 3 is a detail view of the keeper; Fig. 4 is a view of a part of the movable member having the improved bolt mechanism, the parts being shown in rear elevation; Figs. 5, 6 and 7 are plan views of the bolt mechanism illustrating different positions thereof; Fig. 8 is a plan view of the bolt mechanism, omitting the tumblers; Fig. 9 is a cross section on the line 99 of Fig. 5, certain parts being shown in elevation. Fig. 10 is a detail view showing one side of the member for actuating the bolts; Fig. 11 is a cross-section on the, line 1111 of Fig. 9; and Fig. 12 is a vertical section on the line 12-12 of Fig. 9 showing the operating parts of the bolt mechanism.

A designates the movable member of the lock, and B is the keeper. Said movable member is shown as being hingedly connected at c to an attaching plate 0, the latter being fastened in any suitable way to a moving part such as the top or cover D of a trunk. The keeper B is adapted to be fastened to the body D of the trunk. Although I have shown the parts of my lock adapted for use in connection with a trunk and its cover, it will be understood that I do not confine myself to this special use.

The movable member A is of any suitable or preferred construction, but as shown, said member is rounded at its free end, as at a, said rounded end being provided with a flange a. On this end a of the movable member is a casing E for the bolt mechanism, said casing being provided with an annular flange e, which is applied against the inner or rear side of the member A, and is adapted to be secured thereto in any suitable way as by the screw 6, said casing E being secured to the end a of the movable member, and arranged within the flange a thereof.

The keeper B is cast or struck up in a single piece of metal, so as to present, substantially, the annular form shown by Figs. 1 and 3 of the drawings. The keeper is provided with exposed lugs I), through which are adapted to be passed the screws 1), or other fastenings for the attachment of said keeper to the body D of the trunk. The keeper has a raised annular shoulder b adapted to extend around a flat surface b and within this fiat surface is a depression, which produces a ledge b around a circular opening b The casing E is, preferably, substantially circular in cross-section, although this is not material, and said casingis closed at one end and open at the end which is provided with the flange 6. Intermediate its length the casing is reduced in diameter, thereby providing an annular ledge or shoulder e". The closed end of the casing E has an opening f, in which fits a trunnion or stud f of a lever F, the latter being arranged in the contracted inner portion of the casing E. The lever is pivoted at its middle in the casing so as to produce two arms, and to these arms are connected the oppositely movable bolts, G, G. Said bolts are, preferably, of the form shown by Fig. 11 of the drawings, and they are made to work in openings 9, g, formed in the casing E at diametrically opposite points, the other ends of said bo'lts overlapping the lever F, at the respective ends thereof, whereby the bolts G, G, may be connected pivotally at g to said lever.

A spring H is connected to the lever F, and to the casing E, for the purpose of holding said lever in a position to project the beveled ends of said bolts G, G, normally beyond said casing, as shown by Figs. 9 and 11.

I designates a bolt actuator, shown more particularly by Figs. 8 and 10 of the drawings. This actuator is in the form of a disk, which is cut away as at i, to produce the shoulders i. The edge portion 1' rests onand is supported by the annular ledge e of the casing, thus supporting the actuactor ior rotative movement within the casing E. On one side the actuator is thickened below the edge 1'", so as to provide a web or plate j, which fits within the contracted lower part of the casing. On the same side of the actuator as the web, is cast the rib J having the form shown more particularly by Fig. 10. This rib is enlarged at the middle portion thereof,

and the reduced end portions are curved as shown.

The rib oi the bolt actuator fits between the heads of the screws or pivots g which connect the bolts G, G, with the lever F, and said rib J is adapted to retract or withdraw the bolts G, G, simultaneously by a rotative movement of the member or actuator I. It will be understood that the bolts are normally projected by the action of the spring Hon the lever F, but when the actuator or member I is turned in one direction by the key, said actuator operates the rib J, for the purpose of retracting said bolts. The member or actuator Iis provided with a central opening 70, and with an arcuate recess k, the latter being provided in the opposite face of the member I from the rib J; and this member is furthermore provided with a stud K, the latter being adapted for engagement with one or a plurality of tumblers, presently described.

To the shoulder e of the casing is attached a pivotal post 0 and a spring post p, said posts being located to work in the cut out portion 1' of the actuator, (see Fig. 8.) The post 0 is in the path of one of the shoulders i of said actuator, so as to serve as a stop in limiting the rotative movement of the actuator.

A separating plate L is fitted loosely within the enlarged portion of the casing E, so as to rest upon or to engage laterally with the fiat face of the actuator or member I. This separating plate is provided with a ,key opening q, an arcuate slot q, and with apertures adapted to receive the posts 0, p, the latter serving to anchor the separating plate within the casing E, and thereby hold said plate in a stationary position. A plurality of tumblers O are mounted loosely on the post 0, which acts as the pivot for said tumblers. Each tumbler is segmental in shape, as shown by Figs. 5 to 7, inclusive, and each is provided with a notch o, a short finger 1" having a hook r, and a long finger s.

Combined with each tumbler O is a spring P, the same being fitted to the post b, and engaging with the heel of one tumbler O.

T designates a key post which is provided with a slot 13. This key post extends through the separating I plate L, the opening is of the actuator or member I,

and into a recess f which is provided in the lever F.

The tumbler-stud K of the actuator or member I plays in the slot q of the separating plate L, and said stud K is adapted to be received in the notch 0 of the tumblers for the purpose of locking said actuator against movement, and thus prevent the withdrawal of the bolts G, G.

The operation is as follows:-When the cover D is closed the member A and the bolt mechanism are moved opposite to the keeper B on the body of the trunk To fasten the cover D, it is only necessary to press the member A and the bolt mechanism toward the keeper, whereupon the casing E passes through the opening b of said keeper. During such inward movement of the member I the bolts G, G are pressed inward by engagement with the edge of the keeper, and when the member and the bolt mechanism have reached their normal positions, the bolts are again thrown outward by the action of the spring H, whereby the bolt mechanism is made to engage automatically with the keeper, so as to secure the look without requiring the use of a key in fastening the cover D in a locked position. To open the lock a proper key is thrust into the slot t of the post T, and into the recess k of the actuator or member I. When the key is turned, the first operation is to ride against the arms r of the tumblers 0, thereby moving the tumblers from the position'of Fig. 5, back to the position of Fig. 6. A continued movement in the turning of the key makes the member I move the stud K from the position of Fig. 6, to the position of Fig. 7, and during this movement the key clears the short arms 1 of the tumblers and the stud K rides against the long arms s of said tumblers. At the same time the rib J engages with the heads of the pivot screws g for the purpose of turning the lever F, and retracting the bolts G, G, simultaneously, thus releasing the bolt mechanism from engagement with the keeper. The key, the post T, and the member or actuator I, may now be restored to their normal posi: tions, so that the stud K will again engage with the notched portions 0 of the tumblers, thus releasing the bolts G, G, and permitting the key to be withdrawn. The cover D may now be opened, but when it is desired to again lock the trunk or other structure, it is only necessary to press the member A sidewise, for the bolts G, G, to engage automatically with the keeper.

Although I have shown and described my improved lock as adapted for use on trunks, it will be understood that the lock may be used generally on other articles and structures.

An important advantage of my invention is its adaptability to automatically fasten the member A when it is moved into cooperative relation to the keeper, for the reason that the bolts are self-locking by pressing them into said keeper.

Another advantage of my construction is that I employ two bolts adapted to engage with the respective edges of the keeper and to be simultaneously withdrawn by the simple operation of turning the key when thrust into the lock.

Changes in the form, size, proportion, and minor details in construction may be made without departing from the spirit of the invention or sacrificing any of the advantages thereof, and I, therefore, reserve the right to make such alterations and modifications as fairly fall within the scope of my invention.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1.
